1986 Evinrude Motor Leaking Gas

I am looking to buy a 1986 model boat with 70HP evinrude motor. The motor runs great but it leaks a steady stream of gas out the air cleaner at idle speed. If the motor runs a little harder it will quit leaking. Anyone know the cause of this?
 
First off it does not have an " air cleaner "--------There should be a wee hose attached to the silencer box to draw any leakage into the motor.---------------Squeeze the primer bulb to see if it goes hard.-----Any leakage then will mean a float valve is stuck open.----When motor speeds up the leaking fuel from top carburetor would be drawn into the lower carburetors.-------------------The 3 cylinder 86 is a good unit if it has been properly maintained.
